TO START ENGINE (See Fig. 13)
CAUTION:
Keep the tine control in
"OFF'
position when starting engine.
o
Make sure spark plug wire is properiy iconnected.
Move shift lever indicator to "N" (neutral) position_
o
Place throttle control in "FAST" position,
o
Place choke control in "CHOKE" position if the engine
is cold_ A warm engine may not requirechoking to start.
=
Grasp starter handle with one hand and grasp the tiller
with other hand.
Pull rope out slowly until engine
reaches
start of compression
cycle (rope will pull
slightly harder at this point).
°
Pull rope with a rapid, continuous, full arm stroke, Keep
a firm grip on starter handle and let rope rewind slowly.
Do not let starter handle snap back against starter.
o
When engine starts, slowly move choke control on
engine halfway between
CHOKE" and "RUN" posi-
tions and then to RUN position as engine warms up.
°
Move throttle control to desired running position.
o
Allow engine to warm up for a few minutes before
engaging tines.
NOTE;
If at a high altitude (above 3000 feet) or in cold
temperatures
(below 32°F), the carburetor fuel mixture
may need to be adjusted for best engine performance. See
'q'OADJUST
CARBURETOR"

Tilling is digging into, turning over, and breaking up
packed soil before planting. Loose, unpacked soil
helps root growth. Best tilling depth is 4" to 6". A tiller
will also clear the soil of unwanted vegetation. The
decomposition
of this vegetable matter enriches the
soilo Depending on the climate (rainfall and wind)
it
may be advisable to till t he so I at the end of the growing
season to further condition the soil.
°
For easier handling of your tiller, leave about 8 inches
of untilled soil between the first and second tilling
passes.
The third pass will be between the first and
second (See Fig, t4)

Soil conditions are important for proper tilling., Tines will
not readily penetrate dry, hard soil which may contrib-
ute to excessive bounce and difficult handling of your
tiller. Hard soil should be moistened
before tilling
however, extremely wet soil will "ball-up" or clump
during tilling. Wait until the soil is less wet in order' to
achieve the best results. When tilling in the fall remove
vines and long grass to prevent them from wrapping
around the tine shaft and slowing you r tilling operation.
Do not lean on handle. This takes weight off the wheels
and reduces traction,
To get through a really tough
section of sod or hard ground, apply upward pressure
on handle or lower the depth stake..

CULTiVATiNG
Cultivating is destroying the weeds between rows to pre-
vent them from robbing nourishment and moisture from the
plants. At the same time, breaking up the upper layer of soil
crust wilt help retain moisture in the soil. Best digging depth
is 1" to 3". Lower' the outer side shields to protect small
plants from being buried
-
Cultivate up and down the rows at a speed which will
allow tines to uproot weeds and leave the ground in
rough condition, promoting no further growth of weeds
and grass (See Fig, 15),

TINE SHEAR PiNS
The tine assemblies on your tiller are secured to the tine
shaft with shear pins (See 'q'INE REPLACEMENT" in the
Service and Adjustments
section of this manual)°
If the tiller is unusually overloaded or jammed, the shear
pins are designed to break before internal damage occurs
to the transmission.
=
If shear pin(s) break, replace only with those shown in
the Repair Parts section of this manual
